\ SASE CONTROL.

Specification of Letters Patent.

Patented June12, i917.

- To all whom it may concern:

, on the floor.

Be it known that I, JOHN DAVID CoocLE, a citizen of the United States, residing at Corsicana, in the county of Navarro and State of Texas, have invented certain new and useful Improvements in Sash Controls; ,and I do hereby declare the following to be 'a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention relates to builders hardware, and more especially to sash fasteners; and the object of the same is to produce a control by means of which either sash of a window can be adjusted to and fastened in the desired position open or closed. While I have shown the control mechanism as mounted in the casing of the window whose sashes it controls, it will be obvious without further illustration that the control could-be located some distance from the window as when the latter, is a high one on stairwa s or in churches, and the control must e placed within izfach of an operator standing lso I have omitted illustration of any sash weights or other counterbalancing means, as these are not necessary with my invention although it is possible that they could be employed. Details of the invention will be found in the following specification and shown in the drawings wherein i Figure 1 is an inside elevation of a complete window in dotted lines, showing my invention in full lines applied to the two sashes thereof.

Fig. 2 is an enlarged vertical section through the actuating mechanism of the control, and Fig. 3 is a section on the line 3-3 of Fig. 2.

The upper and lower sashes U and L are slidably mounted as usual within the window casing C, as indicated in dotted lines in Fig. 1, and said casing includes outer and inner facings O and I as seen in Fig. 2. It has been common hitherto, and especially where the sashes were counterbalanced wit weights, to raise and lower them by means of cordsand the like attached to one side of the sashes, because counterbalancedsashes do not bind when moved by controlling cords attached in this manner. Also it is of course well known that in order to raise and lower any I member which moves in guides the correct point of attachment of the l fting cord is directly above the center of gravity. I employ thisprinciple for raising the sashes, but alsoutilize cords attached to the side rails'thereof so as to bind or jam the sashes at certain times as will be explained.

Coming now to the details of invention, the actuating mechanism-for this control consists of a housing 'including an inner plate 1 and an outer plate 2 secured respectively within the inner and outer facings I and O of the casing C, the attachment in the presentinstance be1ng by means of screws 3; and in suitable bearings 4L within these plates are mounted upper and lower drums or spools 5 and 6, each having gears 7 on both their heads, and the upper drum being preferably somewhat longer than the lower as seen in Fig. 2, a spacing collar 8 being employed to hold this drum towardthe inner plate 1. I

'Between the drums a power shaft 10 is revolubly and slidably mounted in suitable bearings 14 in the two plates, its forward end having a handle 11 and its rear end projecting beyond the plate 2 and having a head 12 which permits the entire shaft to be drawn forward slightly by pulling on the handle when desired. A gear or pinion17 is fastened on the shaft near the rear plate 2 and in position to be thrown into engagement with either of the gears 7, according as the shaft and the driving pinion are moved in or out. Thereafter rotation of the power shaft by means of its crank handle rotates that drum with which it is in engagement, as will be clear.

Suitable locking means are provided for preventing the rotation of the drums, and in Secured to or formed as part of the rod near its front end is a projection 25 which normally stands in engagement with the teeth of the front gear 7 as seen at the bottom of Fig. 2, but which of course may be thrown out of engagement with the same by ably mounted through holes24 pressing on the knobi21 asseen at the top of the same view. While I have gone into detail with respect to the preferred construction of the parts thus far described, I do not spects as the principal feature of the invention is the manner in which the drums are connected with the sashes, as I will 'now explain.

A 'cord 30 is secured .to and wound in one direction around the drum 5, and led thence upward Within the casing C over a double pulley 31, thence inwardto the transverse center of the casing, over another double pulley 32, and thence downward and connected with the center of the top rail of the. upper sash at the point 33. Another cord 34 is wound in the same direction around the drum 5, led thence'upward within the casing and over a-pulley 35, and carried thence inward toward and attached to the side rail of the upper sash U at a point 36 which is near thebottom of this sash. A cord 40 is 1 secured to the lower drum 6 and wound around it in the same direction as the cord 30, thence it is led upward alongside such cord, over thesame double pulleys 31 and 32, thence downward as at 42, and attached at 43 to the center of the top rail of the lower ward, aroundthe pulley 45, and thence in- I 35 ward to the lower sash L to which it is attached as shown in Fig. 1. a

With the actuating mechanism connected in this manner with the two sashes, the operation of this control is as follows: To

move'theupper sash U, the upper knob 21' is, pressed so that the projection 25 disengages the gear wheel 7 of the upper drum 5. The handle 11 is then grasped and theshaft 10 pushed inward so that the pinion 17 engages the rear gear 7 of said drum 5. Now by turning the handle, in the proper direction the cords 30 and 34 are paid out and the sash U descends by gravity if it has no counter-weights, or may be drawn down by hand. When it has been lowered to a sufiicient extent the finger is removed from the knob 21 and the projection 25 engages the front gear of the drum 5 so that the latter is locked against rotation, and as more cord cannot be paid out, the sash U cannot be opened any farther. It is closed by the sameoperation as described, excepting that the crank would be rotated in the other direction, To raise the lower sash the knob of the lower locking means is pressed on,

the power shaft 10 drawn forward to engage its pinion 17 with the gear 7 of the drum 6, and this drumturned by rotating the handle. As the cord 40 is wound on the drumto raise the sash L, the cord 44 is paid out to an equal extent; and whenfthe drum is again locked against rotation, the sash is locked and can neither be raised. nor

. lowered excepting by the same'mechanism. 5 wish to be'limited unnecessarily in these re- Thus it will be seen that the upper sash descends by gravity and is raised .by direct upward pull on the cord 30--possiblyassisted by the cord 34, whereas the lower sash is raised by direct upward pull onthe cord'42 and descends by gravity-possibly assisted by the cord 44. But attention is directed to the fact that when either sash reaches its closed position under the action of this device, the last rotary impulse on the drum tightens the cord 34 or 44 and strains the sash laterally within its uides so as to prevent it' from rattling an to hold it in place frictionally while the tension of the remaining cord 30 or 40 merely sustains its weight. Also these cords 34 and 44 pass respectively above and below their pulleys 35 and 45 so that. they resistany. eifort'to open the respective sashes.

I have spoken of cords throughout this specification, but obviously chains orother flexible elements are-included. I have shown the sash control in Fig 1 as located at the right side of the casing C and at a point Y within ready reach of an operator standing on the floor, But I do not wish to be limited at all in this respect, and it is quite possible as suggested above that the actuating mechanism could be remote from the window and its casing as for instance where saidwindow is quite high above the floor. Also I have shown and described this sash control as applied to a window having two moving sashes, but I do not wish to be limited in this respect.

WhatIclaimis:

1. A sash movable in upright guides; combined with-a control therefor including a cord leading over pulleys and-attached to the sash vertically above its center of gravity, a second cord attached to one ofthe stiles of said sash, apulley journaled on the sash guide and at such location that when the sash is in closed position the cord end extends substantially perpendicularly from the sash'edge to the respective pulley; and means including a -drum mounted in the sash guide adjacent to said stile to which.

. the cords are attached and wound insimilar ing a gear at one end and a locking wheel at the opposite end, a shift gear, with a shaft having a crank in front of the easing selectively engageable with the driving gears, and independent automatic, yielding locking devices respectively engageable with said locking wheels, and having means exposed in front of the sash for manual selection and operation separately from the shift gear.

3. In a sash control, the combination with sashes and their casing in which the sashes are slidably mounted, of a pair of parallel vertically spaced winding drums within the casing, a shift gear engageable with the drums alternately and having a crank projecting through the casing, sash cords connecting the upper drum to the upper sash, sash cords connecting the lower drum to the lower sash, and independently operable push buttons having shafts with lugs respectively for automatically locking. the drums and springs for shiftlng the shafts axially.

4. In a sash control, the combination with sashes and their casing in which the sashes are slidably mounted, of a pair of parallel vertically spaced winding drums within the casing, vertical, spaced bearing plates supporting the spindles of the drums, a shift gear engageable with the drums alternately and having a crank projecting through the casing, sash cords connecting the upper drum to the upper sash, sash cords connecting the lower drum to the lower sash and push buttons having shafts axially and yieldingly movable in said plates, locking wheels on said drums, and lu'gs on said shafts respectively for automatically locking said wheels and the drums.

In testimony whereof I aflix my signature.
